Note on Gathering of Exiles Trophy/Achievement

You will need a base intelligence of 8 in order to talk to Carhillion of the Fold in No-Man's Wharf. He will not move to Majula until he deems you worthy of interacting with him.

You need Licia (the miracle vendor you meet after defeating the dragonrider in Heide's Tower of Flame) in order to complete the trophy. If you kill her when you meet her, you cannot get the trophy in that playthrough.
